An earthquake or tremor (trus) occurs due to the movement of tectonic plates, the movement of the Earth's crust or the occurrence of an impact, and the consequence is the shaking of the Earth's crust due to the release of high energy. The tectonic plates move 2 to 3 cm per year, but in contrast, earthquakes happen very often. Contrary to the widespread belief that these are rare phenomena, they happen very often, but their greatest number is of low intensity and occurs on relatively small areas of land or the ocean floor. On the earth's surface, earthquakes can manifest as shaking or dislocation of the ground. Sometimes, they can cause a tsunami, a destructive sea wave. Earthquakes occur as a result of the jamming of tectonic plates, where the rock mass is stressed, and the moment the stress becomes so great that the rocks cannot withstand it, it breaks and slides along the fault. Earthquakes can occur naturally or as a result of human activity. Smaller earthquakes can also be caused by volcanic activity, landslides, explosions and nuclear tests. In its broadest sense, the word earthquake is used to describe any seismic event—whether natural or man-made—that generates seismic waves. Earthquakes are among the most terrible natural disasters that occur on Earth, which is why they have attracted the attention of mankind since time immemorial. That is why we find information about earthquakes in thousands of years old records. However, significant studies of earthquakes took place only from the 19th century.

Earthquake definition

An earthquake is the oscillation of soil particles caused by natural or artificial causes. The result is the release of the Earth's internal energy. The common name seismism is used for the set of all seismic phenomena. Seismism or earthquakes are sudden and brief tremors of parts of the earth's crust. An earthquake is a process of release of kinetic energy on a celestial body. An earthquake on our planet is called an earthquake. It happens in the Earth's lithosphere or just below, in the next layer, the so-called the asthenosphere and the mantle, which makes up most of the Earth's mass. Part of the kinetic energy that is dissipated through the lithosphere is called seismic energy and is measured in seismological�
